MEANS FOR- ATTACHING PICKER-STICK CHECKS TO LOOMTLAYS- Specification of Letters Patent.

Application filed October 13, 1920. Serial No. 416,629.

To all whom it may concern:

Be it known that we, JOHN B. FnNNnLL and Enwnnn B. Fnownns, both citizens of the United States, residing in Columbia, in the county of Richland and State of South Carolina, have invented certain new and useful Improvements in Means for Attaching Picker-Stick Checks to Loom-Lays, of which the following is a specification.

Our invention relates to looms of the class in which the picker stir-k is checked in its movement at opposite ends of the lay by devices usually consisting of leather straps suspended from the opposite ends of the lay by brackets or hangers. Experience has demonstrated that the ends of the lay often crack or split where the hangers or brackets are attached owing to the shock or strain imparted to these ends of the lay by the vibrating picker stick and owing also to the fact that hangers are secured to the lay by means of bolts. the heads or which are arranged in mortiscs cut in the lay, the nuts of the bolts being applied to the bolts on the outside of the lay. These mortises are for the purpose of locating the bolt heads out of the paths of the picker sticks as they vibrate in the slots formed in the lay, but these mortises so weaken the lay as to cause the splitting or breaking as above specified. Often the lays thus damaged may be repaired, and this is usually done by attaching a patch to the lay but this requires time and trouble and consequent expense.

We overcome these ditliculties by attaching the'bracketor hanger to the lay in an improved way and without weakening the lay by forming a mortise, as has heretofore been the practice.

In the accompanying drawings:

Figure l is an elevation of a loom lay, portions of the picker sticks and portions ot. the picker stick checks.

Fig. 2 is a perspective View, showing how brackets or hangers are applied to the lay in accordance with our invention.

Fig. 3 illustrates how a damaged lay may be repaired by our improvements.

In Fig. 1, A illustrates a loom lay, B picker sticks, C the straps of the picker checks and D the brackets or hangers for suspending the straps from the lay. The parts so far as shown in Fig. 1 are of well known construction.

According to our invention, when making a new lay we do not mortise it as heretotore but we secure the brackets or hangers to the lay in the manner indicated in Fig. 2. For this purpose we employ a bolt and nut of the kind shown in Fig. 2 and also in Fig. 3. As there shown the bolt M is threaded at opposite ends. At one end it recelves a relatively thin, flat nut m and at 1ts opposite end it receives a nut 71. of the ordinary kind. In applying the bolt and nuts to the lay, the nut m is inserted through the slot 0. in which the picker stick moves, and it is seated in a shallow recess 0. The bolt M is then inserted through a hole in the side of the lay and passed entirely through the side of the lay on one side of the picker stick slot and is made to engage the nut m. This may be done by a screw-driver applied at 9. After this is done the bracket D is applied and then the nut n is screwed home. In this way a secure conmotion is made between the bracket and the lay and as the lay has not been weakened by the formation of a mortise or mortises it is stronger and much more durable.

lVhen an old lay, constructed in the usual manner, is cracked or broken, as shown at a; in Fig. 3, it is repaired in accordance with our invention, in the manner indicated in Fig. 3. We do not find it necessary to cut into the lay and form a mortise or recess to receive a patch, but we apply one of our bolts M with its nuts m and n, in the manner indicated in Fig. 8. The lay repaired in this way is sufliciently strong for all purposes as a rule. Of course, it the lay is badly cracked or damaged it will have to be repaired in some other way or else discarded, but experience has demonstrated that if the lay is repaired, in accordance with our invention, before the crack or break has extended very far it may be made entirely serviceable.

We claim as our invention:

1. The combination with a loom lay having a picker stick slot, of a bracket for suspending a picker check device, a bolt extending entirely through the side of the lay on one side of the picker stick slot and which is threaded at opposite ends, anut arranged in saic. slot and engaging the bolt, and a nut engaging the outer end of the bolt outside the bracket.

2. A loom lay having a slot in which the picker stick moves, and a shallow recess in one Well of said slot, a bracket for suspending 2!, picker stick cheek device, a thin nut arranged in said recess of the lay, a bolt extending entirely through the side of the lay on one side of the picker stick slot and Which is threaded at opposite ends and engages at one end the thin nut and a nut engaging the outer end of the bolt outside the subscribed our names.
